METHOD OF MANUFACTURING WIRE-GLASS Specification of Letters Patent.

Application filed February 16, 1909. Serial No. 78,278

To all whom it may concern:

Be it known that I, 'iLLLut Bn'rrnna, of Indianapolis. in the county of Marion and State of Imiiana. have invented a certain new and useful Improvement in Methods of Manufacturing Wire-(Ellass, of which the following is a full, clear, and exact description, reference being had to the accompanying drawing, forming part of this specitlcw tion, and in which Figure 1 illustrates a vertical section through apparatus which may be used in terizes that form of wire-glass as is manu factnred by that method wherein the wire net-work or trellis is forced downwardly into the molten glass by means of a leading roller having a series of cireumfcreir tial flanges which, as the sheet of glass is being rolled, serve to embed the metallic network in the sheet, while a second plain-faced roller adapted to travel in the rear of the leadin roller, serves to flatten the sheet to its ultimate thickness. This irregular surface imparted to the glass sheet is attributable to the failure of the finishing roller to work the molten glass back into the grooves formed by the ribs or flanges of the leading roller.

My invention consists in breaking down a molten mass of glass and embedding a me tallic net-work or trellis in the sheet at a predetermined distance from the surface thereof by means of a flanged roller in the usual manner--the molten mass of glass, the metallic reinforcing element and the leading roller being indicated by the reference numerals 2, 3, and 4, respectively, while the flattening table is indicated by the numeral 5 in the accompanying drawings-and then flattening and smoothing the sheet by several applications of a finishing rollerstmh as indicated by the numeral (1, In this latter respect is where my invention differs from all other methods of making wire-glass, namely, that in flattening and smpothing the irregular surface formed by the forward roller enr ployed to flatten the batch and embed the metallic reinforcement, the surfacing roller 6 is adapted to be passed several times back and forth over the sheet while the glass is still plastic as distinguished from the customary one" pass of the surfacing roller. The several passes of this finishing roller or rollers in one direction owrate to completely fill the grooves formed by the leading roller, working the glass back and forth, bringing the sheet down to its ultimate thickness and imparting a smooth uniform, brilliant surface to the sheet. This result cannot be obtained by the application of a multiplicity of finishing rollers working in one direction because it is necessary that the surface of the plastic glass be so worked or manipulated as to obliterate all traces of the streaks or grooves formed b the wire embedding roll and which is on y possible by causing the glass to be worked back and forth to insure a )roper flow for the filling or obliteration 0 such streaks. Furthermore, in the forward travel of the finishing roller over the still plastic glass in my process, the

roller becomes warmed or heated, preventing chilling of the glass in its return or subse quent passes. The flow of the glass, therefore, is easy and not strained. In those processes employing several rollers, working in one direction, the successive, applications of the different rollers chill the glass, producing a dull, strained surface in addition to molten glass by means of a roller employing a series of embedding ribs or flanges.

Having described my invention, what I claim and desire to secure by Letters Patent is s 1 1. The hercindeseribed method of manufacturing sheet-glass having a metallic reinforcement embedded therein, which consists in breaking down a batch of molten glass and embedding the metallic reinforcement by means of a roller having a series of peripheral ribs or flanges, then bringing the sheet down to its ultimate thickness bv l working the glass back and Ierth by several applications of a finishing roller.

2. The hereindeseribed method of manufacturing sheet glass having metallic reinforcen'lent embedded therein Which consists in breaking down a batch of molten glass and embedding the metallic reinforcement by means of a roller and then passing a second roller back and forth over the soft glass in order to remove the seams.

In testimony whereof, I have hereunto Set my hand;
